There is currently an issue with using IE in Windows 7 where the confirmation dialog box after completing the step in the “Let Me Try” does not appear and you cannot get pass it to complete the task. This only impacts the “Let Me Try” for the Office 2013 content; the “Let Me Try” for the Office 2010 and computer concepts content work fine. There are no issues with the “Let Me Try” in IE with Windows 8. As a temporary workaround if your students are using Windows 7, please have them use Chrome or Firefox instead of IE. We are working on identifying the root cause and will provide an update as soon as possible.
